Summary: [GTK] Extra check needed at
AccessibilityObject::visiblePositionRangeForRange
Product: WebKit
Version: 528+ (Nightly build)
Platform: PC
OS/Version: Linux
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: Accessibility
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: msanchez at igalia.com
It would be needed to make some extra checks at AccessibilityObject::visiblePositionRangeForRange to make sure toRenderText() function is called with valid parameters, that is, a RenderObject returning 'true when calling to its isText() method.
This check is needed because current code doesn't do it and could be executed with RenderObjects other than instances of the RenderText subclass, resulting in failures such as the one in the following stack trace:

I'm now building WK with a patch for this. Will attach it as soon as I tested it.
